CENTENNIAL, Colo. -- James Holmes remains in solitary confinement in a Colorado jail as prosecutors build their case against him.

A team of lawyers spent about 90 minutes Tuesday inside the movie multiplex in Aurora where Holmes allegedly went on a deadly shooting rampage. Crews started setting up a chain link fence around the building while people continued to flock to a memorial nearby for the victims.

Survivors are offering new details about that night, saying the gunman stalked around the theater shouting and appearing to target people. Holmes is accused of methodically stockpiling weapons and explosives at work and at home that police say he used to kill 12 people and wound 58 more at the theater.

Meanwhile, a profile for a man whose name and appearance matched suspect James Holmes has been removed from a dating website.

Match.com spokesman Matthew Traub on Tuesday confirmed reports on TMZ.com and elsewhere that the profile was posted before the movie theater massacre. Traub would not comment on whether Match.com believes Holmes actually posted the profile.
